User Seal Checks

Always check the seal of the respirator on your face before entering a contaminated area.
Positive Pressure User Seal Check
1. Place the palm of your hand over the opening in the exhalation valve cover and exhale gently.
2. If the facepiece bulges slightly and no air leaks are detected between the face and the facepiece, a proper seal has been obtained (Fig. 11).
3. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and recheck
seal.
If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.
Negative Pressure User Seal Check with 6000 Series Cartridges
1. Place palms of hands to cover face of cartridge or open area of 3M™ Filter Retainer 501and inhale gently. If you feel the facepiece collapse
slightly and pull closer to your face with no leaks between the face and facepiece, a proper seal has been obtained (Fig. 12).
2. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and recheck
seal.
If you cannot achieve a proper seal, DO NOT enter contaminated area. See your supervisor.
